PATENT FRED. GRIMM, OF COMANCHE, TEXAS.

PLOW.

SPECIFICATION forming part of Letters Patent No. 357,279, dated February 8, 1887.

Application tiled October 30,1886. Serial No. 217,612. (No madel.)

.To all whom, it may concern:

Be it known that I, FRED. GRIMM, .avcitizen of the United States, residin-g atComanche, in the county of Comanche and State of Texas, have invented a new and useful Improvement in Flows, of which the following is a specification. v

My invention relates to improvements in plows; and it consists of the peculiar combination and novel construction and arrangement of the various parts for service,` substantially as hereinafter fully described, and particularly pointed out in the claims.

The object of my invention is to provide a plow with means whereby the friction upon the landside thereof is very materially decreased, and the draft is lightened to enable the plow to bei drawn with less effort by the draft-animal.

A further object of my invention is to p1'o vide means which can be applied te the plow 4 for the purposes above named at the time 'of its manufacture, or subsequently thereto after Y it has been sold, and which can be readily adliable to adhere thereto, all as will be more fully described hereinafter. A

In the accompanying drawings, which illustratel a plow embodying my present improvement, Figure l is a side elevation taken from the landside of the plow. Fig. 2 is a bottom plan view. Fig. 3 is a longitudinal sectional view on the line x x of Fig. 2. Fig.' 4. is an enlarged perspective view of my invention. Fig. 5 is a vertical cross-sectional view of the y same on the line g/y of Fig. 4.

Referring to the drawings, in which like letters of reference denote corresponding parts in all theigures, A designates the standard, which is to be bolted or otherwise attached in anv suitable manner to the beam of a plow. Apoint, B, of any approved p'atter'n, and a mold-board, B', are connected to the lower end of the standard in the ordinary manner, and

the forward end of the point is braced by a` landside, Diwhich is also attached or connected to the standard. The landside is made in two sections-a front and rear sectionwhich are joined or connected together at about the point where the horizont-al foot a of the standard A is connected thereto, this foot a being curved and extended forward beneath the point and bearing against the inner sides of the sections of the landside. The foot covers the joint between the sections of the landside, and the latter is bolted thereto to provide a very firm and rigid structure, the heads of the bolts being countersunk in suitable openings in the outer face of the landside, so as to lie flush with the said outer exposed face of the landside,which acts upon the soil.

The point and mold-board are braced by a plate or strap, E, which is arranged on theinner concealed sides thereof and suitably secured to the same, and a horizontal brace, F,

lextends from the landside to the mold-board to brace the outer edge of thelatter, the outer end of the brace F being bent at f, to provide an arm which extends across the joint between the mold-board and point to further brace and strengthen the said point and mold-board.

The rear terminal end of the landside is concaved or curved, as at g, and a roller or wheel, G, is arranged in close proximity to the said curved terminal end of the landside, as shown. This roller or wheel is arranged in line with the landside, and the outer surface thereof is fiat and lies iiush with the exposed outer surface of the landside, so that as the plow is drawn along over the field this roller or wheel will not retard the progress of the same.

The wheel or roller is journaled in a bracketplate, H, which is arranged to one side of the landside, on the inner concealed side thereof. rlhe rear end of the landside can be bent at the time 0f its manufacture to provide or form the bracketplate, or the latter plate can be riveted' to the landside,or Welded thereto, after it has been sold, as will be very readily understood. have shown vthis bracket-plate bolted to the rear end of the landside, and the rear end of the bracket-plate extends or projects in rear of the landside, as shown. This extended rear end of the bracket-plate is provided with a segmental orcurved slot, h, through which an In the accompanying drawings I IOO IOS

t 1o axle J is rounded at the point where the wheel or roller turns or revolves thereon, and the axle is squared, as at j', at the point where it passes through the segmental slot of the bracket-plate, so as to prevent the shaft from partaking ofthe rotary motion of the wheel or roller when the plow is drawn across the field. The extreme inner end of the shaft or axle is again rounded and threaded externally, and on this threaded portion of the shaft is fitted 2o a binding-nut, J', which bears upon a washer, K, that is interposed between the nut and the bracketplate, as clearly shown.

rlhe bracket-plate has a fender, L, bearing upon the upper edge thereof, and which is curved upwardly therefrom and extends over the periphery ofthe roller or wheel G. This fender is of greater width than the wheel and the bracketplate, so as to concealI the upper edges thereof and prevent the dirt or ,soil that 3o is loosened by the plow from passing between the wheel and bracket-plate to the axle, which is liable to cause undue friction on the axle and soon wear the latter away. The rear end of the fender is bent or curved downwardly and beveled, so that it will come in contact with the periphery of the wheel, or nearly so, and thus perform the additionalfunctions of a scraper to clear the wheel from accumulations of earth and other matter thereon. rIhe 4o fender is further provided with a downwardlyextending inclined arm, M, which is provided at its lower end with a transverse opening, m, which aligns with the slot of the bracket-plate H, so that the squared end of the axle or shaft J will pass through the said transverse opening. The said lower end of the arm llI is fitted between the washer and the bracket-plate, and the fender is thus braced by the inclined arm being connected to the bracket-plate by 5o the same axle which carries the roller or wheel G.

rIhe wheel G is of greater diameter than the width ofthe landside of the plow, so that the upper and lower edges of the wheel are projected beyond corresponding edges of the landside; and by thus extending the periphery of the wheel below the lower edge of the landside the latter is elevated out of contact with the earth to decrease the friction thereon and 6o very materially lessen the draft on the plow.

The fender is formed separate from the bracket-plate, and the opening in the lower end of the brace-arm thereof is made square in form, so that the squared portion of the shaft or axle will pass therethrough, whereby when the axle is raised or lowered in the slot of the fixed bracket-plate the arm and the fender will be adjusted with the wheel, and the fender thereby occupies the same relative position to the wheel at all times, so as to protect the same and clear mud and other accumulations therefrom.

The operation of my invention will be readily understood from the foregoing description. Vhen it is desired to move the plow from one field to another, the shaft or axle is lowered in the slot of the fixed bracket-plate by loosening the binding-nut, and thereby depressing the wheel below the lower edge of the landside of the plow, so that when the device is in motion the periphery of the wheel will ride upon the ground and the lower edge ot' the landside will be elevated out of contact therewith, the fender being moved or adjusted simultaneously with the roller or wheel. When the plow reaches the held, the axle is adj usted to the desired height in order to regulate the depth to which the plow will enter the ground; and as the plow is drawn through the ground the landside is slightly raised by the roller or wheel G to lessen the friction on the landside, the said wheel being` arranged iiush with the outer side of the landside to prevent the wheel from retarding the progress of the plow.

I do not desire to confine myself to the exact details of construction and form and proportions of parts herein shown and described as an embodiment of my invention, as I am aware that changes therein can be made.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An attachment for plows, comprising a detachable bracket-plate secured to one side of the landside of a plow, and having a slot, and awheel or roller arranged on one side of the plate and in line with the landside, the shaft or axle of the wheel or roller passing through the slot of the plate and having the threaded inner end provided with a nut, substantially as described, for the purpose set forth.

2. In combination with a landside of a plow, a bracket-plate secured thereto, a roller or wheel in line with the landside, and a fender above the wheel, having the arm connected with the axle of the wheel, substantially as described, for the purpose set forth.

3. An attachment for plows, comprising a bracket-plate having the slot, the roller or wheel, the shaft or axle of the wheel or roller passing through the slot of the bracket-plate, a fender having the inclined brace-arm, and a nut fitted on the threaded end of the shaft and clamping the axle, the fender-arm, and the bracketplate to the landside of a plow, substantially as described, for the purpose set forth.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in presence of two witnesses.

FRED. GRIMM.
